, RUBBEB BUTTON.

Application a a 14, 1925. Serial No. 123,100.

The object of my invention is toprovide a button which will avoid the undesirable features of those types-upon which my button is an improvement.

' In one of these types the rim of the button is too thin and flexible, so that it readily yields to peripheral pressure and folds or cups on a diametric line under normal strains, and then pulls out of the button hole.

In the other type the rim is hard, rigid and inflexible. When such button'is used on washable garments. to be run thru a wringer, and the button becomes positioned crosswise of the rollers of the wringer, either the button is torn offfor it is permanently deformed, folded in V-shape in passing thru the rollers, and tends also to mutilate the resilient covering of the latter.

I attain myobject in a button made of elastic, homogeneous, non-absorbent material consistin of a relatively thick rim substantially in exible and a thinner central web integral with the rim with the maximum thinness of the web at its" centre, the rim adapted to resist bendingand folding on diametric lines under normal pressures, but

toyield to greater pressures.

I have tested the eflicienc of my own button over the first mentione type by using both kinds on wearing apparel; using in one instance a rubber button structurally embodying the principle of my invention, and using on the other hand a button made with a non-yielding middle portion, and having its maximum flexibility at its rim. The first mentioned button-embodying my improvement-stays buttoned; the other becomes repeatedly unfastened. Upon consideration the reason for such difference will be ap-.

40. parent; upon the rim of the buttonis imposed a great leverage of which the middle portion of the button, fastened 'to the garment constitutes the fulcrum; hence the rim should be adapted to offer and capable of offering sufficient resistance to such leverage faces should be provided with recesses in which said strands may lie, and thus not pro ect beyond the planes of said faces by lying within the same. To this end I provide the under face of the button with a concavlty or recess as well as the upper face of the button in which said strands may lie. Such construction incidentally provides for the maximum flexibility of-the button' at its middle portion within its said rim which by contrast renders the rim relatively non-' yielding; or at all events imparts to the rim great resistance to deformation, since the strains imposed on the middle portion of the button provided with the thread receiving holes, will be to some extent dispersed and accommodated by the greater yielding and flexible middle portion ofthe button.

And with respect to the seeond above mentioned type my button has all the advantages thereof, but none of its disadvantages. When my button is used onza washable garment,.the substantially inflexible rim of my button will resist bending and folding on. diametric lines under such pressures as arenormally imposed by the button-hole in the wearing of the garment, but will yield greater than normal pressures; and thus will 845 permit the button to pass, under all condi: tions, between the rollers of a wringer without inju to the button or the resilient cover of t e rollers; the button being merely temporary deformed into V-shape, in case it should become positioned crosswise of the rollers, thus facilitating the passage of the button between the latter; and after the button has passed through the rollers, it will re-assume its normal form and condition.

The construction and features of my improved button are diagrammatically illustrated in the accompanying drawings, in which; p

Fig. 1 is a perspective of my button with a portion thereof broken away, and shown 1n section;

Fig. 2 is a plan view of the top of my button;

Fig. 3 is a plan view of the bottom of my button;

Fig. 4 is a diametric section taken on the line 4-4 of Fig. 2; .and v Fig. 5 is a similar section as Fig. 4 il- 11 lustrating diagrammatically the leverage strains to which my button is more or less subjected in service; and

illustrates further that the substantially non-flexible rim of the button tends to resist; the deformation of the button by said strains, the latter being accommodated by the more flexible middle portion of the button. As apparent the drawings of my improved button are on a very exaggerated scale.

My button is made of rubber compound of suitable resiliency, or may be made of any material which would have the same characteristics as rubber with respect to said resiliency, wear and capability of sustaining the strain of the fastening thread by which the button is fastened to the garment. The rim 0. of the button is made of substantially cross section, and its periphery substantially circular or rounding. The middle portion of the button is recessed as at b on its top, and the bottom of the button is concaved as at c. The button'is provided with holes as (l in which to receive the fastening thread, which in Figs. 4 and 5 is represented by 6. Thus the strands of the fastening thread lying crosswise of the middle portion of the button betweenthe thread receiving holes d, on the underside of the button, will be substantially contained in the space between said underside and the surface of the material to which the button is fastened; the button being in Figs. 4 and 5. Thus, in undering the garment provided with my button, the sadiron will pass over the upper face of the button wit out imposing any wearing strain upon the strands of the fastening thread lyagainst either side. ofthe button.

in i ln the diagrammatic view Fig. 5, the top line g represents the plane of the upper face of the button, the broken line f as mentioned, represents the plane of the lower face .to retain its normal form, neither cupping nor bending under said strain.

I claim:

1. A button of elastic, homogeneous, nonabsorbent material consisting of a relatively thick rim substantially inflexible and a thinner central web integral with the rim, with the maximum thinness of the web at its centre, the rim adapted to resist bending and folding on diametric lines under normal pressures, but to yield to greater pressures.

2. A button of elastic, homogeneous. nonabsorbent material consisting of a relatively thick rim substantially inflexible and a thinner central web integral with the rim adapted to resist bending and folding on diametric lines under normal pressures, but to yield to greater pressures, the central portion of the web lying within the upperand lower faces of the rim.

3. A button of elastic, homogeneous, non-.

absorbent material consisting of ,a relatively thick rim substantially inflexible and a thinner central web integral with the rim adapted to resist bending and folding on diametric lines under normal pressures, but to yield to greater pressures and the upper face of the web lying rim and the under face concaved.
